Pneumatic Design Series Vibrators use an external air motor to drive shaft mounted eccentric weights to produce rotary vibration. Because of their separate motor these vibrators can produce substantial force with moderate frequency.

When harnessed by proper mounting of the Design Series vibrator, this rotary vibration is transferred through the hopper or bin wall to the material within. As the material vibrates, its displacement from the hopper wall reduces friction with the wall and allows gravity to restore material flow. Proper mounting also disperses the rotary vibration over a large area producing uniform material flow. Since rotary vibration is directional, material will be encouraged to flow in the direction of the rotating weight.

Applications:

Motor driven vibrators are more efficient and effective at producing large amounts of force than other types of pneumatic vibrators. They are highly effective at moving large quantities of almost any type of bulk solid from fine, light weight materials to large masses of "stuck" solids, including sand, flour, chemicals, sugar, cement, powders, spices, clay, lignite, coal dust, and many others. It is easy to control the force and frequency by adjusting the air supply.

When the frequency of the vibration matches the natural frequency of the material, enhanced flow can be achieved with a minimum of force.

It is easy to tune a pneumatic Design Series vibrator to the material being handled. Simply increase the speed by gradually adjusting the air flow to the vibrator until material flow is achieved. This way you obtain the maximum result with the minimum of air consumption and vibrator wear. Once the material moves freely, the vibrator can be turned off until it is needed again.

Features:

Produces Uniform, Directional Flow.

High Amplitude, Moderate Frequency vibration.

High Efficiency, Durable, Bi-rotational Pneumatic Motor - Instantly reversible, can be stalled or overloaded without damage, self sealing vanes automatically adjust for their own wear ensuring constant output for thousands of hours.

Versatile - Easy to control force and frequency by adjusting air supply.

Available in Permanent Mount and Portable Clamp-on Mount. Clamp-on vibrators use square head set screws with concave cup points for positive self-locking and vibration resistance.

Unique drive coupling protects motor shaft, vibrator shaft, bearings and seals from stress and unbalanced load of the weights; prevents air leaks; and gives longer life. Finest design available anywhere.

Easy repair and maintenance - designed for easy change-out of bearings, motors, couplings, and other components to refurbish Design Series vibrators to like new condition. Bearings, o-rings, retaining rings, etc. are standard, commonly available parts. Air Motor Repair Kits available to return motor to like-new condition.

Five-Year Warranty.

Options:

Adjustable weights available on C3, D4.5, & CC4.5 models.

Roller bearings available on D4.5 & CC4.5 models to give speeds up to 7,500 RPM with intermittent use. Roller bearings give 5 times greater life than standard bearings. Roller bearing models have special oil lubrication system and vented covers to minimize heat build-up and transfer heat away from the bearings.

Operating Requirements:

Filtered and lubricated air.

8-80 PSI depending on size. 30-114 CFM.

Maximum Ambient Temperature = 250°F (120°C).

Vibrator Selection:

Selection based on the weight of the material in the sloped portion of the container.

In general, select the pneumatic Design Series vibrator capable of producing a force equal to one-tenth the weight of the material when the vibrator is operating at medium pressure (40-60 psi / 2.8-4.1 bar).
